Additional functions (Pr. 59)
<Setting>
Use Pr. 59 to select whether the remote setting function is used or not and whether the speed setting storage
function* in the remote setting mode is used or not. When "1" or "2" is set in Pr. 59, the functions of signals RH, RM
and RL are changed to acceleration (RH), deceleration (RM) and clear (RL), respectively. Use Pr. 180 to Pr. 183
and Pr. 187 (input terminal function selection) to set signals RH, RM and RL.
* Speed setting storage function (Pr. 59 = "1")
This function stores the remotely-set speed (speed set by RH/RM operation) into memory. When power is
switched off once, then on, operation is resumed with that output speed value.
<Speed setting storage conditions>
• Speed at which the start signal (STF or STR) turns off is stored.
• The remotely-set speed is stored every one minute after one minute has elapsed since turn off (on) of both the
RH (acceleration) and RM (deceleration) signals. (The speed is written if the present speed value compared with
the past speed value every one minute is different.) (The state of the RL signal dose not affect writing.)
REMARKS
This function is invalid under jog operation and PID control operation.
Even when the remotely-set speed is cleared by turning on the RL (clear) signal after turn off (on) of both the RH and RM
signals, the inverter operates at the remotely-set speed stored in the last operation if power is reapplied before one minute has
elapsed since turn off (on) of both the RH and RM signals.
When the remotely-set speed is cleared by turning on the RL (clear) signal after turn off (on) of both the RH and RM signals,
the inverter operates at the speed in the remotely-set speed cleared state if power is reapplied after one minute has elapsed
since turn off (on) of both the RH and RM signals.
